AIR-VALVE.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed February 21, 1910. Serial No. 545,008.

COW/06TH.

Be it known that a citizen of the United States, residing at Chicago, in the county ot Cook and State of Illinois, have invented a certain new and useful Improvement in Air-Valves, of which the following is a specification. I

My invention relates to improvements 1n air valves, and is illustrated in the accompanying drawings, wherein Figure 1 is a section showing the valve closed; Fig. 2, a section showing the valve open; Fig. 3, a section along the line 3-3 of Fig. 1; Fig. A, a section along the line A-fl of Fig. l; Fig. 5, a sectional view of a modiication.

Like parts are indicated by like letters in all the figures.

The casing A has at its top the sleeve A1, which is provided with the screw-threaded cap A3 and screw-threaded plug A3. The base B has the chamber B1 which is closed atthe bottom by the screw-threaded plug B2 and communicates with the pipe B3 by means of the opening B4, and is adapted to be separated therefrom by the door B5 rotating about the rod B3. The casing A and the base B inclose a chamber C which is separated from the chamber B1 by the funnel-shaped partition C1 and which communicates with the pipe B3 by means of the passageway C2. 'Ihe float D carries the valve rod D1 having at its top the valve D2 adapted to engage the valve seat D3 in the plug A3 and to close the passageway D4. The valve E supported upon the float D by means of the members E1 is adapted to close the opening E3 in the partition wall C1, and carries the rod E3 which is connected by means of the shatt E4 with the bucket E5 which is mounted upon the shaft EG within the chamber B1. The expansion member F is supported by means of the rod F1, collar F2 and arms F3 upon the base B.

In the modification illustrated in Fig. 5 the connection between the pipe B3 and the chambers B1 and C is by means of the passageways Gr, G1 instead of the passageway C2 and opening B4. v

It will, of course, be evident that while I have shown in my drawings an operative device, still many changes might be made in the arrangement, shape and size of the parts without departing materially from the spirit of my invention, and I wish, therefore, that my drawings be considered as diagrammatic.

The use and operation of my device are as follows: I provide an air valve having the usual ioat and expansion member, but in addition I provide means for positively retracting the float to prevent its becoming stuck within the casing when in a closed position. These means comprise a chamber below the float chamber, a valve connection between such chambers and a water receptacle within such lower chamber, said receptacle adapted to be filled with water from the upper chamber when the air valve is in its closed position and when so illed to draw down the float in such manner as to open the air valve. I provide means for the egress of water Jfrom such auxiliary chamber comprising a swinging door which door is closed during the movement of the air thro-ugh the air valve and open only when such movement has ceased and water is being discharged from the float chamber. In order to provide place for the valve connection between such chambers it is necessary to change in some way the support Jfor the eX- pansion member and this I have done by supporting the member upon a plurality of arms bearing upon the walls of the supporting base.

In the modification Iprovide two passages instead of the one and do away with the swinging door.

I claim 1. In an air valve the combination with a casing, float and valve member of automat-ic means in addition to the weight of the float and valve member for positively unseating said valve member.

2. In an air valve the combination with a casing, float and valve member of wateractuated means in addition to the weight of the float and valve member for positively unseating said valve member.

3. In an air 'valve the combination with a casing, float and valve member of intermittently operative automatic means in addition to the weight of the float and valve member for positively unseating said valve member.

4. In an air valve the combination with a casing, float and valve member of intermittently operative water-actuated means in addition to the weight of the float and valve member for positively unseating said valve member.

5. In an air valve the combination with a casing, Heat and valve member of automatic means in addition to the weight of the Heat and valve member for positively unseating said valve member, said means including a plurality of chambers, one 0I" said chambers containing the Heat. l

In an air valve, the combination with a I I each connected to said pipe, and having a passage between them, one of them containing the Heat, the other a pivotally mounted bucket, a connection between said Heat and said bucket and a valve member upon such connection to close said passage.

18. An air valve comprising a casing, valve member, Heat and supporting pipe, a plurality of chambers within such casing, cach connected to said pipe, and having a passage between them, one of them containing the Heat, the other a pivotally mounted bucket, a connection between said Heat and said bucket and a valve member upon such connection to close said passage, and means for closing the connection from one of said 4chambers to said pipe.

1st. In an air valve the combination with a casing, Heat and valve member of automatic means attached to the Heat for positively unseating the valve member.

15. In an air valve the combination with a casing, Heat and valve member of wateractuated means attached te the Heat for positively unseating the valve member.

16. In an air valve the combination with a casing, Heat and valve member et' intermittently operative automatic means attached to the Heat for positively unseating the valve member.

17. In an air valve the combination with a casing, Heat and valve member of wateratcuated means attached te the Heat for positively unseating the valve member, said means intermittently operative.

n air valve having a Heat, a Heat chamber, said chamber having a conical, centrally perforated bottom, a valve mounted upon said Heat and adapted to engage said perforation an air valve mounted upon said Heat in opposition te a seat at the top of the Heat chamber and a bucket beneath said perforation.

19. An air valve comprising a casing, valve member, Heat and supporting' pipe, a plurality of chambers within such casing, each connected to said pipe, and having a passage between them, one of them containing the Heat, the other a pivotally mounted bucket, a connection between said Heat and said bucket, and a valve member upon such connection te close said passage attached to said Heat.
